Creating profile image module in magento 2

1. Create folders under magento root

<magento root>/code/<vendor>/<module>/

2. Create a file ‘registration.php’ and put the below contents in it

\Magento\Framework\Component\ComponentRegistrar::register(\Magento\Framework\Component\ComponentRegistrar::MODULE,'<vendor>_<module>',__DIR__);

3. Create folder ‘etc’ and create file ‘module.xml’ in it,, and put the below content in it.

<?xml version="1.0"?>

<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Module/etc/module.xsd">

<module name="<vendor>_<module>" setup_version="1.0.0">

</module>

</config>

4. Create a route for the controllers which are needed to be made. Create e folder ‘frontend’ in etc folder and create file ‘routes.xml’ in it, and enter the following details in it.

<?xml version="1.0" ?>

<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:App/etc/routes.xsd">

<router id="standard">

<route frontName="<route_path>" id="<route_path>">

<module name="<vendor>_<module>"/>

</route>

</router>

</config>

5. Create folder ‘Controller’ and create two folder in it.

‘Delete’ and ‘Index’. Create Index.php in both of it.

6. In Delete -> Index.php , paste the following code

namespace <vendor>\<module>\Controller\Delete;

use Magento\Framework\App\Filesystem\DirectoryList;

class Index extends \Magento\Framework\App\Action\Action

{

protected $_filesystem;

protected $image;

protected $_file;

public function __construct(

\Magento\Framework\App\Action\Context $context,

\<vendor>\<module>\Block\Imageprofile $image,

\Magento\Framework\Filesystem\Driver\File $file,

\Magento\Framework\Filesystem $fileSystem

) {

parent::__construct($context);

$this->image = $image;

$this->_file = $file;

$this->_filesystem = $fileSystem;

}

public function execute(){

$fileName = 'IMG_'.$this->image->currentUser()->getId();

$mediaRootDir = $this->_filesystem->getDirectoryRead(DirectoryList::MEDIA)->getAbsolutePath('images/'.$this->image->currentUser()->getId().'/');

if ($this->_file->isExists($mediaRootDir.$fileName)) {

$this->_file->deleteFile($mediaRootDir.$fileName);

}

$this->_redirect('customer/account/');

}

}

7. In Index -> Index.php , paste the following code

namespace <vendor>\<module>\Controller\Index;

use Magento\Framework\App\Filesystem\DirectoryList;

class Index extends \Magento\Framework\App\Action\Action

{

protected $_filesystem;

protected $image;

public function __construct(

\Magento\Framework\App\Action\Context $context,

\Magento\Framework\Filesystem $fileSystem,

\<vendor>\<module>\Block\Imageprofile $image

) {

parent::__construct($context);

$this->_filesystem = $fileSystem;

$this->image = $image;

}

public function execute()

{

$result = array();

if ($_FILES['profile_image']['name']) {

try {

// init uploader model.

$uploader = $this->_objectManager->create(

'Magento\MediaStorage\Model\File\Uploader',

['fileId' => 'profile_image']

);

$uploader->setAllowedExtensions(['jpg', 'jpeg', 'png']);

$uploader->setAllowRenameFiles(true);

$uploader->setFilesDispersion(false);

// get media directory

$mediaDirectory = $this->_filesystem->getDirectoryRead(DirectoryList::MEDIA);

// save the image to media directory

$result = $uploader->save($mediaDirectory->getAbsolutePath('images/'.$this->image->currentUser()->getId().'/'),'IMG_'.$this->image->currentUser()->getId());

} catch (Exception $e) {

\Zend_Debug::dump($e->getMessage());

}

}

$this->_redirect('customer/account/');

//echo "Hello";

}

}

8. Finally create a folder named ‘Block’ and create a file ‘Imageprofile.php’ in it. Paste the following code in it.

namespace <vendor>\<module>\Block;

use Magento\Framework\App\Filesystem\DirectoryList;

class Imageprofile extends \Magento\Framework\View\Element\Template

{

protected $customerSession;

protected $_file;

public function __construct(

\Magento\Backend\Block\Template\Context $context,

\Magento\Customer\Model\Session $customerSession,

\Magento\Framework\Filesystem\Driver\File $file,

array $data = []

)

{

parent::__construct($context,$data);

$this->customerSession = $customerSession;

$this->_file = $file;

}

public function currentUser()

{

return $this->customerSession->getCustomer();//->getId();

}

public function getMediaUrl()

{

$mediaUrl = $this->_storeManager

->getStore()

->getBaseUrl(\Magento\Framework\UrlInterface::URL_TYPE_MEDIA);

return $mediaUrl;

}

public function checkExist()

{

$filename = 'IMG_'.$this->currentUser()->getId();

$filepath = $this->_filesystem->getDirectoryRead(DirectoryList::MEDIA)->getAbsolutePath('images/'.$this->currentUser()->getId().'/');

if ($this->_file->isExists($filepath.$filename)) {

return 1;

}else{

return 0;

}

//return $filepath.$filename;

}

}
